- Mask all MSI-X entries when enabling MSI-X otherwise stale unmasked entries stay around e.g. when a crashkernel is booted. - Enforce masking of a MSI-X table entry when updating it, which mandatory according to speification - Ensure that writes to MSI[-X} tables are flushed. - Prevent invalid bits being set in the MSI mask register - Properly serialize modifications to the mask cache and the mask register for multi-MSI. - Cure the violation of the affinity setting rules on X86 during interrupt startup which can cause lost and stale interrupts. Move the initial affinity setting ahead of actualy enabling the interrupt. - Ensure that MSI interrupts are completely torn down before freeing them in the error handling case. - Prevent an array out of bounds access in the irq timings code. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmEY5bcTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoaMvD/9KeK2430f4h/x/fQhHmHHIJOv3kqmB gRXX4RV+N/DfU9GSflbzPxY9l2SkydgpQjHeGnqpV7DYRIu84nVYAuWcWtPimHHy JxapniLlQv2GS+SIy9f1mmChH6VUPS05brHxKSqAQZvQIoZqza8vF3umZlV7eYF4 uZFd86TCbDFsBxbsKmyV1FtQLo008EeEp8dtZ/1cZ9Fbp0M/mQkuu7aTNqY0qWwZ rAoGyE4PjDR+yf87XjE5z7hMs2vfUjiGXg7Kbp30NPKGcRyasb+SlHVKcvZKJIji Y0Bk/SOyqoj1Co3U+cEaWolB1MeGff4nP+Xx8xvyNklKxxs1+92Z7L1RElXIc0cL kmUehUSf5JuJ83B6ucAYbmnXKNw1XB00PaMy7iSxsYekTXJx+t0b+Rt6o0R3inWB xUWbIVmoL2uF1oOAb6mEc3wDNMBVkY33e9l2jD0PUPxKXZ730MVeojWJ8FGFiPOT 9+aCRLjZHV5slVQAgLnlpcrseJLuUei6HLVwRXxv19Bz5L+HuAXUxWL9h74SRuE9 14kH63aXSVDlcYyW7c3t8Lh6QjKAf7AIz0iG+u3n09IWyURd4agHuKOl5itileZB BK9NuRrNgmr2nEKG461Suc6GojLBXc1ih3ak+MG+O4iaLxnhapTjW3Weqr+OVXr+ SrIjoxjpEk2ECA== =yf3u -----END PGP SIGNATURE----- Merge tag 'irq-urgent-2021-08-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq fixes from Thomas Gleixner: "A set of fixes for PCI/MSI and x86 interrupt startup: - Mask all MSI-X entries when enabling MSI-X otherwise stale unmasked entries stay around e.g. when a crashkernel is booted. - Enforce masking of a MSI-X table entry when updating it, which mandatory according to speification - Ensure that writes to MSI[-X} tables are flushed. - Prevent invalid bits being set in the MSI mask register - Properly serialize modifications to the mask cache and the mask register for multi-MSI. - Cure the violation of the affinity setting rules on X86 during interrupt startup which can cause lost and stale interrupts.
